ZXLD1350EV4 LAYOUT
The top and bottom view of the evaluation board is shown here. The slugs of the 1-watt LEDs are connected to
isolated copper 'floods' both on the top and bottom layers, with thermal inter-connection between the layers. The
slugs are electrically isolated from other circuits and pads on the evaluation board.
